Before making any 76ers vs. Celtics picks, you NEED to check out the NBA predictions from the SportsLine Projection Model.

The SportsLine Projection Model simulates every NBA game 10,000 times and has returned well over $10,000 in profit for $100 players on its top-rated NBA picks over the past four seasons. The model went a stunning 88-60 on all top-rated NBA picks last season, returning more than $2,100. Anyone following it has seen HUGE returns!

The model knows the 76ers are elite on the offensive end. With three top-level shot creators, Philadelphia led the NBA in free throw accuracy last season (82.1%) and also finished in the top three in free throw attempts per game. The 76ers are also great at maintaining ball security, committing fewer than 13 turnovers per game, and Philadelphia should benefit from a full season with James Harden alongside Joel Embiid. 

The model also knows Boston is the reigning Eastern Conference champion. The Celtics posted the best defensive performance of any team in the NBA last season, giving up only 1.06 points per possession. Boston also led the league in shooting efficiency allowed, with the No. 2 mark in blocked shots per game.

Now, it has set its sights on 76ers vs. Celtics. We can tell you the model is leaning Under the total, and it also says one side of the spread hits well over 50% of the time! You ABSOLUTELY need to see it before locking in any NBA picks.
